I have a weird issue that only seems to be affecting Awesomenauts. Recently upgraded my gpu to a GTX 1080 and when I open Awesomenauts right after the screen where it shows that you have loaded the game assets and logged into the matchmaking server I get a coil whine sound for a second or two and then the computer power cycles. Sometimes after the coil whine, it will make it into the game and the game plays without issue, but this is only about 10% of the time. Awesomenauts is the only game I am having an issue with, I can play DOOM, Witcher 3, Battlefield One, PUBG, and all my other games without issue. Heat and % utilization seem normal.
